Immersion Ultrasonic Vibration Transducer Rod 1050W 28kHz 40kHz 1050mm Rod Length SUS304 Immersible Sonicator Tube for Tank Cleaning

360-Degree Radial Cavitation for Process Tanks, Chemical Dispersion, Defoaming, and Industrial Cleaning

The GH21105 cylindrical immersible ultrasonic transducer rod delivers uniform radial cavitation throughout processing tanks, reactors, and industrial cleaning systems. Standard planar immersible transducer packs emit acoustic waves in a single directional axis. In contrast, this cylindrical configuration radiates ultrasonic energy in a 360-degree perimeter, eliminating acoustic dead zones and accelerating physical and chemical reactions in liquids.

The complete setup comprises a 1050 mm hermetically sealed stainless steel vibration rod containing 21 matched piezoelectric transducers, paired with an external separate-excitation digital generator. The system supports full manual power regulation, sweep frequency tracking, pulse mode, and liquid degassing.

Technical Specifications

Vessel Integration and Mounting Methods

The integrated mounting flange allows direct fluid-tight installation into open reservoirs or pressurized closed vessels:

• Top-Mount Installation: Suspended vertically through an open tank rim or top access port. Suited for immersion cleaning lines and open extraction tanks.
• Bottom-Mount Installation: Secured through a flange port at the tank base. Acoustic energy projects upward through the liquid column to maintain active agitation without occupying upper workspace.
• Side-Mount Installation: Bolted horizontally through vessel sidewalls or inline processing conduits. Suited for continuous fluid circulation lines and deep reservoirs.

Mandatory Operating Requirement: The active rod body must remain fully submerged in liquid during operation. Operating the system dry causes rapid overheating and permanent damage to internal piezoelectric elements.

Application Engineering & Frequency Selection

1. Frequency Selection

• 28 kHz (60 mm Rod Diameter): Heavy-Duty Cleaning
  Generates large cavitation bubbles that release high mechanical impact energy upon collapse. Applied to remove heavy grease, carbon deposits, oxide scale, and particulate contamination from metal castings, engine parts, and heavy tooling.
• 40 kHz (50 mm Rod Diameter): Fine Cleaning & Sonochemistry
  Produces high bubble density with moderate collapse pressure. Applied to precision machined components, optical parts, electronics, laboratory mixing, and delicate surface treatment.

2. Liquid Degassing and Defoaming

Alternating acoustic pressure waves cause entrained micro-bubbles to coalesce into larger gas bubbles that rise quickly to the fluid surface. This method eliminates air pockets in coatings, inks, paints, resins, and food emulsions without adding chemical antifoaming agents.

3. Dispersion, Emulsification, and Extraction

Intense fluid shear stress created by cavitation breaks down particle agglomerates, homogenizes immiscible liquid phases into stable emulsions, and disrupts cellular membranes to speed up botanical and chemical extraction processes.

Quality Control and Manufacturing Standards

• Piezoelectric Array Matching: Transducer elements undergo resonance frequency and electrical impedance matching before internal mounting to maintain balanced energy distribution across all 21 units.
• Hermetic TIG Welding: Robotic welding seals the tube body and mounting flange. Finished rods undergo pressure submersion testing to verify fluid-tight containment.
• Continuous Load Testing: Each transducer rod completes a full-load submerged burn-in test before shipment to verify thermal stability and generator frequency locking.
• Export Packaging: Transducer rods are packed in reinforced export wooden crates to prevent shaft bending. Supporting generators are packaged in high-density foam-lined cartons.

Manufacturer Profile & OEM Customization

Granbo Technology Industrial Shenzhen Co., Ltd. was established in 2013 in Bao’an District, Shenzhen. Supported by an R&D team with over 20 years of experience in industrial ultrasound engineering, Granbo manages complete custom fabrication workflows:

1. Parameter Definition: Specify tank dimensions, liquid volume, chemical medium, operating temperature, and process targets (cleaning, emulsification, or defoaming).
2. Configuration Matching: Select operating frequency (28 kHz or 40 kHz), tube diameter (60 mm or 50 mm), rod length, and metallurgy (SUS304, SUS316, or Titanium).
3. Mechanical Confirmation: Confirm flange specifications, cable length, and generator interface requirements.
4. Production & Delivery: Manufacturing, electrical testing, crating, and shipment by air, sea, or express freight.

Compliance & Operating Guidelines

International Certifications

• Quality Management: ISO 9001:2015 Registered
• Safety & Electromagnetic Compatibility: CE Certified, FCC Compliant
• Environmental Safety: RoHS Compliant

Operational Guidelines

• Submersion: Never power the transducer rod without full liquid coverage.
• Workpiece Spacing: Maintain a clearance of at least 2 mm between treated parts and the rod surface to prevent localized erosion and maintain uniform acoustic fields.
• Chemical Compatibility: Standard SUS304 stainless steel is intended for neutral and mildly alkaline cleaning media. Corrosive acids or strong alkalis require SUS316 or titanium construction.
• Thermal Management: The equipment supports extended duty cycles. After prolonged continuous runs under high loads, pause operation for at least 3 minutes to permit cooling.
• Generator Protection: Install the separate-excitation generator in a dry area free from liquid splashes and corrosive fumes.
